If Jake Paul could go back in time with his current skill set could he win UFC 1? He is quite possibly the most well rounded fighter with his elite boxing skills and Ohio state qualifier in wrestling.
Being a 200lb wrestler with pro boxing skills I think he’s a bad match up for Royce unless Royce can somehow get a heel hook before being knocked unconscious. Obviously he outwrestles art jimmerson and KOs Ken Shamrock. I don’t see anyone at UFC 1 posing a threat to the legendary warrior known as Jake Paul.
The answer is no. Royce Gracie defeated Art Jimmerson (a boxer) by tap out. He then defeated Ken Shamrock (shootfighter, wrestler) by submission. In the finals of UFC 1, he defeated a Kyokushin/Savate fighter, Gerard Gordeau by submission as well.
